Watch Post Malone Play Eric Johnson's "Cliffs of Dover"

The fact that hip-hop/pop superstar Post Malone is an impressive guitarist is no state secret at this point.

However, it's one thing to flash some chops here and there, and another entirely to tackle Eric Johnson's "Cliffs of Dover," the instrumental masterpiece that remains one of the most beautiful, and difficult-to-perfect, guitar workouts of all time.

Not one to back away from a challenge, Malone recently took to Instagram to demonstrate some of the song's trademark licks with his Les Paul. You can check out his version below.

Malone posted the video as a challenge of sorts to his producer and musical partner in crime, Andrew Watt, who manned the boards and played lead guitar on Ozzy Osbourne's Ordinary Man.

In response, Watt posted a video of his own, tearing into his solo on Osbourne's "Take What You Want," which also happens to feature Malone on vocals.

You can check out his solo in the video below.
